I had to make a similar decision a couple if weeks ago, I chose the Galliera GM even though I could have gotten 2 other LV bags for the same price.
It's a shoulder bag.
I love the unique, fresh, trendy look.
It just felt right when I tried it on.
I needed an every day bag and I know that I would never carry a hand-held bag every day.
Just go to LV and try the different bags, youll find out what suits you more.
I'm still thinking about getting a speedy though, but I know I made the right decision (for myself) to get the Galliera first.
